Since the 1990s, the Federal Trade Commission (FTC) has negotiated settlement agreements addressing privacy with many companies. Although the FTC’s authority is limited, the agency has developed detailed rules about privacy and data security.

The U.S. and the EU define “personally identifiable information” (PII) differently. Their rules for protecting PII also differ which cause challenges for global businesses. To bridge these privacy law differences, the authors propose a tiered system (PII 2.0) that they say will make compliance easier without sacrificing protections.
